  • Publication number: 20090264268
    Abstract: Method and arrangement for controlling the temperature of two cylinders forming a nip. The temperature of at least one point on each cylinder is sensed by sensors, forming a point of measuring, wherein the highest sensed temperature is used as set point and wherein the cylinders are heated in areas where the sensed temperature is below the set point.

  • Publication number: 20020052274
    Abstract: A variable heat transfer system and a passive, segmented hold-down mechanism for a preheater section and a hotplate section of a machine for manufacturing corrugated board. The preheater assembly having the variable heat transfer system includes a plurality of actuators to urge a continuous web of material toward a preheater drum. A sacrificial material is positioned between the web of material on the preheater drum and the actuators. In response to moisture detection in the material by a plurality of sensors, one or more of the actuators applies variable pressure in the cross-machine direction to the wet portion of the material. Also, the passive, segmented hold-down mechanism includes a plurality of independently weighted feet for varying a variable pressure profile in the cross-machine direction formed upon the web of corrugated board. The hold-down mechanism compensates for variations in the contour of the surface of the hotplate section.

  • Publication number: 20020004442
    Abstract: A low thermal inertia die (10) must be heated to a specific set temperature to cut/seal plastics material. As heat energy is dissipated during cutting/sealing it is replaced by an equivalent amount of thermal energy from an electrical heating element (26) embedded in the die, adjacent the profiled working face (22) which in use contacts plastics material. The element (26) is covered in electrically non-conductive tape (28) and encased in flattened steel tube (30). A thermocouple (32) is also embedded in the die (10), with its tip (34) located to sense the temperature of a central region of the working face (22). The electrical current supplied to the electrical resistance heating element (26) is controlled in dependence upon the temperature sensed.

  • Patent number: 6238326
    Abstract: To regulate the temperature of the heated air in an apparatus for the pasting of plastic films having a rack having a table over which the workpieces are conveyed continuously by a conveyor apparatus, having a conveyor roller pair disposed in a gap of the table top and supported in the rack, consisting of a lower counter-pressure roller and an upper suction cylinder, having a conveyor cylinder acting together with the suction cylinder which successively transfers sections to the suction cylinder, and having a broad-slit nozzle directed to the roller gap which blows in a controlled manner heated air to the roller gap, the temperature directly after the pasting of the pasted region of the workpiece at which a good pasting occurs is determined as the nominal value and the temperature of the heated air is regulated to this nominal value.

  • Patent number: 5653428
    Abstract: A phase control system for a fan blade assembly of a folder is provided which includes a fan blade assembly, a folded product transport assembly, and a control system. The fan blade assembly includes a first and second rotating fan blade assembly. The first rotating fan blade assembly has a plurality of first fan blades and has a first circumference. The second rotating fan blade assembly includes a plurality of second fan blades and has a second circumference. A product receiving area is defined at an intersection of the first and second circumferences such that only one of the first and second fan blades can occupy the product receiving area at any instant. The folded product transport assembly is provided for delivering folded products to the product receiving area. The control system includes a first sensor, a second sensor, and a fan blade assembly motor actuator.

  • Patent number: 4850944
    Abstract: Apparatus for heat sealing the respective layers of film in a pair of hems in a moving web of film in the manufacture of draw tape bags. A pair of hot air hem sealer units is provided each of the units including a hot air hem sealer heat exchanger having a plurality of nozzles which direct hot air against a continuously moving film. The nozzles are in line with film movement and the film is backed up by a metal plate positioned between the hems. Following the heating phase cool compressed air is directed against the film in the heated area to cool the film prior to contact with the hem seal on the other side of the bag. The heat exchanger includes a plurality of circumferential grooves which deliver hot air to the nozzles. A thermocouple controls the temperature of the hot air.

  • Patent number: 4512133
    Abstract: An apparatus for sterilizing a thermoplastic strip moving forward stepwise and used in the production of hot-formed containers which, after forming, are filled and sealed in a sterile atmosphere, wherein prior to the strip softening operation, the surface of said strip which is subsequently to constitute the inside face of the containers, is exposed evenly and intermittently, in successive portions and for a very short period of time, to a temperature higher than that of the softening point of the said thermoplastic strip and which is dependent on the desired extent of bacterial destruction.
